Abstract (en)
[origin: WO2021064177A1] Soil-working machine (1) comprising a chassis (2) equipped at the front with a hitch and at the rear with a member (4) for controlling the level of the chassis (2) with respect to the soil, and, mounted on said chassis (2), rows (5) of discs (7) each extending in a transverse direction to the advancing direction of the chassis (2), each row (5) of discs (7) comprising a beam (6) extending in a transverse direction to the advancing direction of the chassis (2), and discs (7) mounted on the beam (6) so as to oscillate with respect to the beam (6). The machine comprises a front member (8) for controlling the working depth. The number of rows (5) of discs (7) is at least equal to three, and the beam (6) carrying the discs (7) of at least one of the rows (5) of discs (7) is a beam (6) mounted movably in position with respect to the chassis (2).
